Duplex ultrasound

Duplex ultrasound allows physicians to measure the velocity of blood flow to many parts of the body. It can also tell the width of a blood vessel and reveal any blockages. Duplex ultrasound combines traditional ultrasound with Doppler ultrasound and is a less invasive option than arteriography and venography.

Duplex ultrasound is used to detect the presence and severity of numerous conditions, including:

Thrombosis (blood clots);

Blockages from atherosclerosis (hardening of the arteries);

Thrombophlebitis (an inflammation of the blood vessels);

Trauma to an artery or vein;

Raynaud's phenomenon (a spasm of small blood vessels in the fingers); and

Providence Health & Services in Oregon is a not-for-profit Catholic network of hospitals, care centers, health plans, physicians, clinics, home health care and affiliated services guided by a Mission of caring that the Sisters of Providence began in the West nearly 160 years ago.
